NF EN ISO 22097, P75-228 (06/2023)

This document describes a set of procedures for using existing test and calculation methods standardized by CEN and ISO to determine the thermal performance of reflective insulation products. This document supports existing CEN and ISO test methods, but is not intended to replace them. This document applies to any thermal insulation product for which part of the declared thermal properties is linked to the presence of one or more reflective or low-emissivity surfaces, as well as to any associated air gap. It does not replace existing procedures for determining the thermal performance of products already covered by an existing harmonized product standard when the declared value of these products does not specifically include declared properties attributable to the emissivity of the facings. It does not, and cannot, specify any use or calculation values of thermal performance, but it provides standardized information for determining these values.
